Damit, Maybe I should start reading the manual... I've built so many ARFs, that the manuals usually only get referenced if something doesn't make sense.. Even with the extra plywood rib, I still wouldn't of had enough clearance though. I would have needed two or more. There is plenty of extra balsa that can be removed from the flaring though so I was sort of lucky...

Did anyone else skip this step and run into trouble like I did?
